Anti-sigma factor that inhibits the activity of the extracytoplasmic function (ECF) sigma-E factor (RpoE), thereby indirectly regulating the transcription of the cycA and rpoE genes. ECF sigma factors are held in an inactive form by a cognate anti-sigma factor.

Also known as Anti-sigma-E factor ChrR (Sigma-E anti-sigma factor ChrR) (Transcriptional activator ChrR).Anti-sigma factor that inhibits the activity of the extracytoplasmic function (ECF) sigma-E factor (RpoE), thereby indirectly regulating the transcription of the cycA and rpoE genes. ECF sigma factors are held in an inactive form by a cognate anti-sigma factor.

Also known as Anti-sigma-E factor RseA (Regulator of SigE) (Sigma-E anti-sigma factor RseA).An anti-sigma factor for extracytoplasmic function (ECF) sigma factor SigE. ECF sigma factors are held in an inactive form by an anti-sigma factor ().
